A cannabis-derived ingredient commonly found in sleep gummies may be more habit-forming than previously thought, with new research showing that repeated exposure caused tolerance and withdrawal symptoms in mice. Scientists warn that CBN may carry risks similar to THC, although its long-term effects in humans remain largely unknown.
Scientists have discovered a surprising two-way relationship between sleep and growth hormone, revealing how the brain carefully balances physical recovery with wakefulness.

Sleep deprivation is seen these days as a major health issue - not least of all in Japan where people sleep less on average than in any other OECD country. Now, a new contest for "competitive sleepers" is hoping to encourage people to snooze for longer. The Tokyo competition, dubbed "Matt Race", saw dozens of participants fitted with sleep tracking devices sprawl on comfy mattresses to slumber for up to 90 minutes Monday, competing for the top prize of over two million yen ($14,000).
Scientists discovered a surprising energy paradox in the brain during REM sleep, the stage most closely associated with dreaming. Blood supply to the brain begins increasing even before REM starts, but neurons’ immediately available energy, measured as ATP, then drops. The finding suggests that dreaming may require such intense internal processing that neurons consume energy faster than it can be replenished.
A large study tracking more than 95,000 people suggests that how you sleep may be linked to your risk of developing dozens of diseases. People who spent more time in REM sleep had lower risks of 83 conditions, including dementia, heart failure, and Parkinson’s disease, while more deep sleep was associated with lower risks of conditions such as type 2 diabetes and major depression.

We would be sleeping alongside sculptures by the renowned land artist Andy Goldsworthy. First, I watch Rivers and Tide
